Lack of data validation - Path Traversal In chromium-browser

Description

The function ParseVP9SuperFrameIndex in common/libwebm_util.cc in libwebm through 2018-01-30 does not validate the child_frame_length data obtained from a .webm file, which allows remote attackers to cause an information leak or a denial of service (heap-based buffer over-read and later out-of-bounds write), or possibly have unspecified other impact.

Mitigation

Update Impact

Minimal update. May introduce new vulnerabilities or breaking changes.
